If you look at actual intersex or genital development stuff, the clitdick makes the most sense and if you want balls, they would be in the pussy lips. In theory, one could be born as a chimera that's perfectly half male/half female, or where a female fetus absorbs nearly all of their male twin except a functional cock and balls on top of vagina.

Overall, it's just fantasy play, make it however you like.
